python - Drawing sine curve in Memory-Used view of Task Manager on Windows 10? -

i trying write simple proof-of-concept script on windows 10 let's me draw absolute of sin curve in task manager memory window.

my code follows:

import time import math import gc import sys  x = 1 string_drawer = []  while true:      #formula eqaution (sin curve)     y = (abs(math.sin(math.radians(100*x))))*512000000     print (y, type(y))      #making y type 'int' can used append     y = int(round(y))     print (y, type(y))      #checking size of string_drawer debugging     print(sys.getsizeof(string_drawer))      #loop used appending     if sys.getsizeof(string_drawer) < y: #if y bigger, find difference , append         y = y - sys.getsizeof(string_drawer)         string_drawer.append(' ' *y)     elif sys.getsizeof(string_drawer) > y: #if y smaller, delete variable , make new 1         string_drawer = [] *y     else: #if y same size string_drawer, nothing         string_drawer = string_drawer      #call python gerbage colector     gc.collect()      #sleep make sure task manager catches change in ram usage     time.sleep(0.5)      #increment x     x += 1     print(x, type(x)) 

what getting follows:

what want this:

do have idea of doing wrong? guess is within if loop or regarding garbage collector.

any appreciated. :)

sys.getsizeof(string_drawer) 

return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific.

only memory consumption directly attributed object accounted for, not memory consumption of objects refers to.

and appending list of strings getsizeof return memory attributed list not size of strings of spaces refers to. change list string

string_drawer = '' string_drawer += ' ' * y 

but can , should use len instead of sys.getsizeof because later adds size of garbage collector (although if string large enough negligible), if want nothing nothing, remove lines:

else: #if y same size string_drawer, nothing     string_drawer = string_drawer 

and reset string string_drawer = '', not list string_drawer = [] * y

update: since python 3.6.2 sys.getsizeof changed account size of referenced objects too.

bpo-12414: sys.getsizeof() on code object returns sizes includes code struct , sizes of objects references. patch dong-hee na.
